Abstract:Objective To evaluate the influence of long-term efficacy in single-level and two-level Bryan artificial disc replacement for treating cervical degenerative disease.Methods Weretrospective analyzed 101 levels in 86 patient sunderwent single-level or two-level Bryan artificial disc replacement in our hospital between December 2003 and December 2007,and followed up for more than 10 years.The mean age was (53.9±9.3)years including 51 males and 35 females.According to the number of the operation level,the patients were divided into two groups:71 levels in group of single-level and 30 levels in group of two-levels.Clinical evaluation indexes included JOA score,NDI index and Odom's standard.Radiographic evaluationindexes included theglobal and segmental range of motion(ROM),segmental COBB's angle.Results The preoper ative global ROM was (45.90±15.18)°,and was (46.31±13.03)°at last fellow-up.The preoperative segmental ROM was (9.67±4.54)°and was (8.63±5.34)°at last follow-up.The preoperative segmental COBB's angle was (2.13±1.32)°,and was (1.23±1.92)°at last fellow-up.The preoper ative global ROM was(40.14±11.59)°,and was (38.33±12.31)° at last fellow-up.The preoperative segmental ROM was (9.10±4.00)°,and was(6.51±4.61)°at last fellow-up.The preoperative segmental COBB's angle was(3.09±2.15)°,and was(0.44±4.62)°at last fellow-up.In single-level group,the improvement rate of JOA score was(69.40±36.80)%,NDI decreased by(12.06±8.20)% and the satisfaction rate of Odom's standard was 91.5%.In two-level group,the improvement rate of JOA score was(59.44±59.80)%,NDI% decreased by(12.53±9.47)% and the satisfaction rate of Odom's standard was 80.0%.The global ROM in single-level group was higher than two-level group(P<0.05).The difference of other indexes was not statistically significantin two groups.Conclusion Both single-level and two-level Bryan cervical artificial disc replacement have the satisfied long-term efficacy in treating cervical degenerative diseases,the postoperative global ROM after long-term of single-level group is higher than those of two-level group.
